On Tuesday, he was ordered held without bond during his first appearance court hearing.

Kenyatta Simario Grant, 21, of Lauderhill, was arrested Saturday and is also charged with felony murder.

He, too, is being held without bond in the Broward Main Jail in Fort Lauderdale.

The two men had been the focus of an intense search since the early morning hours of Sept. 20. Two surveillance videos and several photographs generated numerous tips that helped identify Tyson as one of the suspects, investigators said.

Tyson is seen in one surveillance video discharging a container of pepper spray into the face of a man at a Jamaica-themed party outside the Café 27 Tiki Bar, at the Seminole Truck Stop on the 4600 block of U.S. 27 in Weston, about 2:15 a.m.

As the cloud of toxic fumes spread through the crowd, people scattered.

A man BSO identified as Grant is seen trying to snatch a silver chain and medallion from the neck of the intended robbery victim who had been sprayed in the face. He ran off right behind the second suspect as the victim retrieved a gun from a car and started to chase the two suspects. He stopped when he saw an off-duty Florida Highway Patrol trooper providing security, detectives said.

In the commotion, 28-year-old Kimberly Clarke, of Plantation, inhaled the spray, struggled to breathe, and cried out for help as she fell to the ground and struck her head on the bumper of a parked van, according to the investigative report.

About 20 minutes later, witnesses realized she was unconscious on the ground and called for help. Broward Sheriff Fire Rescue paramedics took Clarke to the hospital in critical condition.

She had arranged to meet friends at the party and arrived only minutes before the pepper spray attack, according to her mother, Marjorie Crossfield.

Clarke, who had a heart condition, never regained consciousness and died Sept. 29 at Weston's Cleveland Clinic.

At the time, a grieving Crossfield wished the man responsible for her daughter's death would turn himself in.

"He knows he did wrong," she said. "He didn't intend to kill anyone, but he's responsible, no doubt."

Her wish came true when Tyson showed up at the Ron Cochran Public Safety Building on Monday afternoon.

His face was seen in a second surveillance video that was released shortly before Clarke's death. It clearly showed Tyson at the truck stop convenience store about two hours before pepper spraying the crowd, detectives said.

Grant was tracked down through a series of leads, sheriff's officials said.

He had been arrested three times this year, for DUI and leaving the scene of an accident, loitering and driving with a suspended license, according to Florida Department of Law Enforcement records.

Tyson had been arrested for burglary and strong-arm robbery, FDLE records show.

Clarke, a native of Jamaica, was a graduate of South Plantation High School and had a degree in criminology.
